Just to clarift, you can / should use the rear heater / demister?
Thats a good point, but the problem also he didnt clean the glass properly and looks like there is a little what i would call dirty water between tint that has dried so showing a cloud so to speak... hes gonna sort it ( hopefully) after the respray..
the clouding you can see is water under the film and thats normal . i used to have little stickers that said ( this @*!# will dry ). lol im sure he will sort it for you
Thanks sly...hopefully
